  > An array of length 0 starts at 0 and ends with 0 But such an array does not "start" at 0 as it does not exist. You need an array of at least length-1 to "start" at 0.

    I can write a loop like this: `for(int i=0; i < 0; ++i)` and it will run 0 times, the exact amount of times I expected

      But again your not starting at "index 0" of an array that exists. This loop is not processing any physically existing array. In fact the compiler would remove this block of code as it is a no-op.
